    1992 DR250s carburetor

    I'm pretty sure that the carb is a VM32-33, not 33-34, I don't believe there is such an animal. And yes, they changed it from the stock 250 to a 170. FlamingLodge's DR is a 1 year newer twin to mine and I may go to the VM32-33 depending on how it performs with new pilot jet.

    1992 DR250s carburetor

    I am currently fighting with the BST31 Unicorn on my '93 DR250. I might have found the right combination of main and pilot for my 7,000 ft elevation but not sure yet. IF I didn't get it right this time, the BST31 will be for sale (it also sat in a barn for a number of years but rebuilt OK, only problem is altitude sickness.) PS, the gas tank was rusted out, replaced with a Clarke.

    1992 DR250s carburetor

    Hmmm, maybe that's what I need for my DR250. Where do I find an adapter from the carb to the intake (engine)?
  4. No, it is not a two stroke...but when I roll off the throttle at 6,000 rpms, it sounds like my Stihl chain saw at idle, 'burbling' merrily. It idles OK but I have to have the idle set a little high to keep it running smooth. The carb and muffler are stock, K&N filter, jets are stock as well. I'm at about 6,000 ft elevation here in New Mexico. Oh, it also seems to run best when it is cold, not as much 'two stroking'. So do these symptoms sound familiar to anyone? I just watched a YouTube of a 250SE and it sounds a little like mine when the rider rolled off the throttle a little. Could this be natural? I don't recall this bike doing that at 1000' in Tejas.

    '93 DR250SE altitude sickness

    OK, I think the factory service manual is wrong after looking at the exploded view of what they call a 'TM31.' It is nothing like the CV carb on my 250. As for the size, I had two 350s and I think they used the same carb as the 250. Again, my bike and the carb are in NM and I'm in TX, won't get a chance to measure the bore until November. BUT back to my original question: is there an adjustable needle available for the BST carbs? The way mine is running, I suspect I need to run a size or two smaller jet and/or drop the needle if possible.

    '93 DR250SE altitude sickness

    Well, I'm fairly sure it still has the original carb and the manual says it is a TM31SS with a 125 main jet as stock. I don't have the carb here or I'd measure it....no model number found on the carb itself, just going by what the service manual says for a '93 DR250SE. The service manual claims a BST33SS with a main of 132.5 as stock for a DR250 (kick start). Where are you getting conflicting information and what 'should' the stock carb be? Oh, airbox is intact.

    23 views and not one opinion? what the heck?

    '93 DR250SE altitude sickness

    I'm sure this has been covered here but a search turned up nothing. So flame away if you wish or make some suggestions if you are so inclined. I've relocated my DR from about 1200 ft to almost 6500 ft. I'll be riding it from 6500, from Ruidoso, NM, to the roads and trails around Cloudcroft at 8600 and up. So currently it has a 130 main, not sure what the pilot is, and stock '1 position clip.' I turned the air screw out about 1/4 turn and it helped but not totally. It runs good at WFO but stumbles and wants to die from idle to 1/2 throttle or so (about where the needle is no longer doing much.) I'm wondering about a multi-position needle dropped a notch and is one available for the TM31 (stock carb obviously.) Since it seems to run OK on the 130 main jet, do I need to screw with the pilot jet and/or the needle?

    1992 suzuki dr250 suspension, newb needs help

    Bump Has anyone tried the Race Tech springs? I would just as soon have Progressive but I guess they don't make them for the 250, at least not the 1993-5 models. Anyone know if the 350 forks/springs for that era would work in the 250?

    1993 DR 250 hasn't been started in 4 years!

    Last (I hope!) request for knowledge from the group. The DR runs great 'MOST' of the time. In fact, ALL MOST all the time. But on four occasions during three rides of about 20 to 40 miles each, it has quit running just as though the fuel was shut off (no stumble like it was running out of fuel and needed to be switched to reserve). But before it coasted to a stop, it fired again and ran, then did the same thing within a couple minutes. Same thing on another ride, two 'incidents'. The third ride was without incident and occurred in between the other two. My guess is some little bit of junk floating around that gets into the main jet and then finds its way out again quickly, then back in and out. I know, sounds weird but so is the problem. Any suggestions will be considered (I really don't want to pull the carb again, it is a bear to get back on but....)

    alright guys lets see ur dr's! put up some pics!

    This is BarnE, a '93 DR250SE rescued from a barn in the Texas Panhandle after sitting for four years. What's with the tiny photos?

    Never mind. I figured it out.

    Need some (more) assistance from the group: I rebuilt the stock CV carb but am not getting any fuel to the spark plug. I am getting fuel into the bowl and no overflow so I'm fairly certain the float system is working properly. The carb is extremely difficult to get on and off the intake boot so I was as careful as I could be to get everything clean before it went on. I know this is a difficult question as there could be a number of reasons for the issue. All the jets are new and all passages were cleaned to best of my ability before buttoning it up and installing it.

    Found the only real issue so far: the idle jet is apparently frozen in place. It is hard to get at since it lives down in a 'well.' I've been soaking it in carb cleaner and other 'stuff,' any other suggestions? I guess I could drill it and use an EZ out. Never mind. I didn't even have to drill it, just used a very small EZ Out and PB Blaster.

    Gas cap is off; PB Blaster, love that stuff!
